Most mobile phones now have a recording function, which means that a mobile phone placed on a table may be used by opponents to record conversations. Therefore, it is very important to have a reliable device to protect the content of private conversations. A recording jammer can do it for you. You only need to turn on the switch button, and the recording jammer will emit ultrasonic waves that exceed the threshold of human hearing and harmless to humans. The microphones in digital devices such as mobile phones and voice recorders will be affected by the recording jammer. Difficult to restore.
Shenzhou Mingda has been engaged in the field of military and police information security for 14 years. It has a large number of national-level large conference rooms, offices, secret vehicles and other special confidential places information security assurance experience, and has extensive experience in anti-eavesdropping and wiretapping investigations. It mainly provides users with: anti-eavesdropping and secrecy detection for government and enterprises, anti-sneak camera detection for hotels, anti-location detection for vehicles, personal home privacy detection, and anti-recording products [recording jammer].
Recording jammers use ultrasonic interference and white noise to prevent recording. Ultrasonic interference mode. Ultrasound is a sound frequency that is emitted at a frequency that is not perceivable by the human ear. It has no harm or impact on the human body, but it will cause huge interference to all equipment that relies on the pickup to record sound. The frequency band it emits impacts the pickup film of the pickup head of audio and video equipment, causing irregular frequency fluctuations on the pickup film, so that the sound recorded by these devices is completely irregular noise. This is its basic principle. Its advantage is that it is silent and safe for humans.
The most effective way to prevent recording is to generate random noise signals through recording jammers, which can suppress the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. The original information is output to ensure the security of the voice information. The recording jammer adopts security encryption processing, and effectively prevents post-recovery by mixing high and low frequency audio sources. Whether it is a variety of wired and wireless pickups, microphones, as long as it is a capacitive pickup, it can be completely interfered by a recording jammer.
As an indispensable product in the construction of information security, recording jammers are playing an increasingly important role in the construction of information security. As the front end of voice information collection, it starts with the protection of information collection, making illegal voice collection behavior impossible, making the collected voice information in a chaotic state, and thus invalid, effectively preventing illegal recording. The user is also very simple to use, just turn on the phone.
